Problem uploading sketches in Surface Pro 4

Hi,

I have bought a Arduino Uno kit some year ago and used it for simple exercise applications. After 3 years not using it, i have reinstalled the IDE and trying to use it with the same Surface Pro 4 i have used in the past.

I see the Arduino connected on the COM5, but not able to upload the sketches.

I have tried on another PC and ot works well.

I have read solution on web and tried everything but not able to make it work.

Any suggestion?

Thanks in advance for your help
Francesco

What exactly happens when you try to upload a sketch ?
